Ladies and Gentlemen:

This letter agreement (this “Agreement”) sets forth the commitments of TPG Partners VII, L.P., a Delaware limited partnership (the “Fund”), subject to the terms and conditions contained herein, to purchase, directly or indirectly, certain equity interests of Osteon Holdings, L.P., a newly formed limited partnership (“Parent”) with de minimis assets. It is contemplated that, pursuant to that certain Agreement and Plan of Merger (as amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), dated as of the date hereof, by and among Exactech, Inc., a Florida corporation (the “Company”), Parent and Osteon Merger Sub, Inc., a Florida corporation and a wholly-owned direct or indirect Subsidiary of Parent (“Merger Sub”), Merger Sub will be merged with and into the Company (the “Merger”), with the Company being the surviving entity of such Merger and a wholly-owned direct or indirect subsidiary of Parent, on the terms and subject to the conditions set forth in the Merger Agreement. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

1.    Commitments. The Fund hereby commits (its “Commitment”), subject to the terms and conditions set forth herein, that, at or prior to the Closing, it shall purchase, or shall cause the purchase of, directly or indirectly through one or more intermediate entities, equity securities of Parent with an aggregate purchase price not to exceed $624,704,000, which will be used to either (i) fund all amounts required to be paid by the Parent at the Closing pursuant to Section 2.02 of the Merger Agreement (the “Closing Commitment”), or (ii) fund the amount of monetary damages required to be paid by Merger Sub in accordance with Section 9.12(c)(iv) of the Merger Agreement (the “Damages Commitment”) (but, for the avoidance of doubt, not both of clause (i) and clause (ii)).

2.    Conditions. The Fund’s Closing Commitment shall be subject to (i) the execution and delivery of the Merger Agreement by the Company, (ii) the continued satisfaction or waiver of each of the conditions set forth in Section 7.01 and Section 7.03 of the Merger Agreement (in each case, other than any conditions that by their nature are to be satisfied at the Closing, but subject to the prior or substantially concurrent satisfaction or waiver of such conditions) and (iii) the substantially simultaneous consummation of the Merger in accordance with the terms of the Merger Agreement. The Fund’s Damages Commitment shall be subject to (i) the execution and delivery of the Merger Agreement by the Company, (ii) the continued satisfaction or waiver of each of the conditions set forth in Section 7.01 and Section 7.03 of the Merger Agreement (in each case, other than any conditions that by their nature are to be satisfied at the Closing, but subject to the prior or substantially concurrent satisfaction or waiver of such conditions) and (iii) a final judgment awarding monetary damages being entered against Parent in accordance with

Section 9.12(c)(iv) of the Merger Agreement and the Merger not having been consummated within the three (3) Business Day period set forth therein. The Fund may allocate all or a portion of its investment to other Persons; provided, however, that no such allocation shall reduce its Commitment hereunder or limit its obligations in respect of the Closing Commitment or the Damages Commitment unless such Persons actually contribute proceeds to Parent and such proceeds are used to fund the amounts described in Section 1 above. If the amount required to be paid by Parent pursuant to the Merger Agreement is less than the Fund’s Closing Commitment, its Closing Commitment hereunder will be reduced on a dollar-for-dollar basis accordingly, and if the amount of monetary damages required to be paid pursuant to Section 9.12(c)(iv) of the Merger Agreement is less than the Fund’s Damages Commitment, its Damages Commitment will be reduced on a dollar-for-dollar basis accordingly.

the Retained Claims, it shall not, and it shall cause its Affiliates, its security holders and their respective Affiliates not to, institute any proceeding or bring any claim in any way under, in connection with or in any manner related to any Transaction-Related Matter (whether at law or in equity, whether sounding in contract, tort, statute or otherwise) against any Non-Recourse Party.
